How can I improve the crema of my coffee using my pump espresso machine?

The secret to achieving a good crema in your coffee is to use fresh coffee and be sure to use an espresso grind. When tamping the coffee, be sure not to compact the grounds too tightly so water can flow through the ground. Be sure not to overfill the coffee filter; using 1 measuring scoop per coffee is recommended. Make sure the coffee filter is clean by trying a different one.
